T5-P6..W..EV-BAC • en • v1.0 • 04.2012 • Subject to changes www.belimo.com Characterised control valves (CCV) with adjustable flow rate, sensor-operated flow control and monitoring P6..W..EV-BAC Product features Principle of operation Flow rate curves The actuator is comprised of four components: characterised control valve (CCV), measuring pipe with medium velocity sensor, temperature sensors and the actuator itself. First of all, the maximum flow rate (max) is set on the actuator, whereby max is permitted to represent 45% to 100% of the greatest possible flow rate nom. At the same time, the max value is assigned to the maximum positioning signal (typically 10 V). Because of the fact that the characterised control valve (CCV) exhibits an equal percentage valve characteristic curve, the positioning signal for the flow rate is also depicted in equal percentages, i.e. 70% of the positioning signal corresponds to 38% of the max value. The actuator control can be either communicative or analogue. The medium flows in the measuring pipe with a velocity of up to 2 m/s, is detected by the sensor and is applied as the flow value. The measured value is compared with the setpoint. Depending on the deviation, the actuator moves the ball of the characterised control valve (CCV) into the required position and acts as a throttling device. The angle of rotation α varies according to the differential pressure through the final controlling element (see volumetric flow curves). ∆p α1 < α2 < α3 α1 α2 α3 Power and energy monitoring function Data recording Manual override High functional reliability Home position Parameterisation Recommended installation positions www.belimo.com max The angle of rotation (α) will differ, depending on the differential pressure (∆p) and the volumetric flow required (), The actuator is equipped with two temperature sensors. One sensor (T2) is integrated in the measuring pipe, the second sensor (T1) is enclosed with the system, already wired, and must be installed in the water circulation at the site. The sensors are used to record the medium temperatures of the supply and return lines of the consumer (heat/cold register). As the water quantity is also known thanks to the volumetric flow measurement integrated in the system, the power released from the consumer can be calculated. Furthermore, the heating/cooling energy is also determined automatically by means of the evaluation of the power over time. The current data, e.g. temperatures, volumetric flow volumes, exchanger energy consumption, etc. can be recorded and accessed at any time by means of web browsers or communication (BACnet or MP bus). The recorded data (integrated data recording for 13 months) can be used for the optimisation of the overall system and for the determination of the performance of the consumer. Download csv files through web browser. Manual override with push-button possible (the gear is disengaged for as long as the key is pressed or remains locked). The actuator is overload-protected, requires no limit switches and automatically stops when the end stop is reached. The actuator moves to the home position when the supply voltage is switched on for the first time, i.e. at the time of commissioning or after pressing the «gear disengagement» key, The actuator then moves into the position defined by the positioning signal. The parameterisation can be carried out simply and rapidly through the integrated web server. The actuator can be installed standing to lying. The characterised control valve may not be installed in a hanging position i.e. with the spindle pointing downwards.

The use of dirt filters is recommended in order to prolong their service life as modulating instruments. Maintenance • Ball valves, rotary actuators and sensors are maintenance-free. • Before any kind of service work is carried out, it is essential to isolate the rotary actuator from the power supply (by disconnecting the power lead). Any pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow everything to cool down first if necessary and reduce the system pressure to ambient pressure level). • The system must not undergo recommissioning until the ball valve and the rotary actuator have been properly reassembled according to the instructions and the pipeline has been refilled in the proper manner. Direction of flow Installation in the return Inlet section The direction of flow, specified by an arrow on the housing, is to be complied with, since otherwise the flow rate will be measured incorrectly. As a general rule, the device is to be installed in the return. In order to achieve the specified measuring accuracy, a flow-calming section or inflow section in the direction of the flow is to be provided upstream from the measuring pipe flange. Its dimensions should be at least 5 x DN. DN Inlet section 65 80 100 125 150 5 x 65 mm = 325 mm 5 x 80 mm = 400 mm 5 x 100 mm = 500 mm 5 x 125 mm = 625 mm 5 x 150 mm = 750 mm ≥ 5 x DN Earthing Valve design /8 It is imperative that the measuring pipe be correctly earthed in order to ensure that the medium velocity sensor does not make any unnecessary incorrect measurements. If no hydraulic data are available, then the same valve DN can be selected as the heat exchanger connection DN. If the valve is assigned to the last consumer, then the pressure drop in the measuring pipe is 30 kPa with nom. If the flow rate is 50% of the nom, then the pressure drop for the length of the measuring pipe will be only ¼ and equals around 8 kPa. (The measuring pipe/valve pressure drop ratio is 58:42) T5-P6..W..EV-BAC • en • v1.0 • 04.2012 • Subject to changes www.belimo.com P6..W..EV-BAC Characterised control valves (CCV) with adjustable flow rate, sensor-operated flow control and monitoring Installation instructions (continued) Installation of immersion sleeve and temperature sensor The valve is equipped with two temperature sensors: • T2: One sensor is already mounted in the valve unit. • T1: The second sensor must be mounted at the installation site ahead of the consumer (valve in the return line; recommended) or after the consumer (valve in the supply line).

Flow rate measurement/setting Q Principle of operation EV V Heat exchanger transfer response 1 Depending on the construction, temperature spread, medium and hydraulic circuit, the power Q is not proportional to the volumetric flow of the water (curve 1). With the classical type of temperature control, an attempt is made to maintain the control signal Y proportional to the power Q (curve 2) and is achieved by means of an equal-percentage valve characteristic curve (curve 3). 2 3 Y /8 T5-P6..W..EV-BAC • en • v1.0 • 04.2012 • Subject to changes www.belimo.com P6..W..EV-BAC Characterised control valves (CCV) with adjustable flow rate, sensor-operated flow control and monitoring Flow rate measurement/setting (continued) Control characteristics The specially configured control parameters in connection with the precise velocity sensor – ensure a stable quality of control.

This range is overridden electronically. Opening valve The valve remains closed until the volumetric flow required by the positioning signal Y corresponds to 2.5% of max. The control along the valve characteristic curve is active after this value has been exceeded. Closing valve The control along the valve characteristic curve is active up to the required flow rate of 2.5% of nom. Once the level falls below this value, the flow rate is maintained at 2.5% of nom.
